Browser Helper Objects are Internet Explorer plug-ins that can change the behavior of Internet Explorer. If a malicious Browser Helper Object is installed, it can make Internet Explorer act strangely, or do significant damage.

While a search of the Internet will reveal many tools for removing Browser Helper Objects, you may not be able to stay connected long enough to find them.

I have scripted DisableHelperObjects.bat to disable, or enable, Browser Helper Objects on your computer.

The syntax for using DisableHelperObjects.bat is:

DisableHelperObjects D|E|L \[ALL|ObjectNumber\]

Where:

L              lists all Browser Helper Object along with their associated ObjectNumber.

D ALL          disables all Browser Helper Objects.

D ObjectNumber disables the ObjectNumber Browser Helper Object.

E ALL          enables all Browser Helper Objects.

E ObjectNumber enables the ObjectNumber Browser Helper Object.

NOTE: Before using DisableHelperObjects.bat, close all instances of Internet Explorer.

DisableHelperObjects.bat contains:

\{L\} goto OK1
if \{%2\}
\{\} goto err

\{D\} goto OK1
